There really doesn't appear to be enough info for us to help you. I suggest starting with simple smaller models (such as a single triangle or small mesh of triangles). If you are able to reproduce the issue with a smaller model but still unable to determine the source of the problem, then post it here so that someone can take a look at it. -Paul
